  • To add to this: A certain type of Soviet submarine used a lead-bismuth alloy as coolant for their reactor. The coolant solidifies at ambient temperature so it had to be heated indefinitely by some way or another or else it solidified and trashed the reactor. I don’t think any of them exist anymore since Russia wasn’t able to afford sustaining the giant navy after the Soviet collapse.

    Just goes to show how insane nuclear submarine engineering is, or was at some point.










  • For me it was migrating my Arch install from EXT4 to ZFS. GRUB had to be configured in particular ways to get it to work with ZFS and I didn’t do it properly so it wouldn’t/couldn’t boot.

    Then I updated ZFS to a version that wasn’t supported by GRUB yet so I chrooted into my installation to switch to Systemd-boot with Unified Kernel Images. Now I still can’t figure out how to add a boot entry for Windows. I followed the proper steps I think but selecting the Windows entry just reloads Systemd-boot.
